This could just possibly be a reaction to the laughing gas. Laughing gas does tend to make you very unconscious to what is going on around you and will make your body seem tired and heavy. Your brain has probably recovered but your body is still recovering from this. Although, your symptoms could be something completely different so the I would advise you to see a doctor.
Dear, please reconsult the Oral Surgeon like yesterday. Don't waste your time on the internet trying to figure out what when wrong.
Sounds like a nerve issue.
GET HELP NOW.
It could be a nerve among-st other things call the Oral surgeon that pulled your teeth and tell him what's going on.
